It takes only 3 tokens to participate and we're earning tons and tons of them. It takes zeroeffort to hoard a huge amount of them and even when I started playng I was never short of them. Ever. They are pretty much useless righ now.
Here are my ideas of what can be done:

- Remove Arena Tokens completely.
Like I said it takes zero effort to earn them so we don't really care for these tokens.

- Nerf token earning. Higher price for entering the arena.
So having tokens and being able to participate takes some effort and is rewarding.

-Make them a spendable currency.
Another shop for tokens perhaps? Or an option to echange Arena Tokens for Manticora Beetles.
